[McIDAS #LSJ-196213]: Converting to netCDF

Hi Carol,

re: running a version of ncdump that gets built with McIDAS

OK, thanks for the info.

re:
> This machine is running the version of 'ncdump' that gets built as part of
> a McIDAS installation.... hum

That version should have worked fine.

re:

This is to be expected if you are copying an entire image and the image
is a full disk scan since there will be a lot of space in the scan.

This all looks OK to me.

To check the netCDF file, I would try displaying the image in it using
an application that works with netCDF as input, something like the
IDV.

re:

No worries.

Cheers,
